[Age-related characteristics of capsular angioarchitectonics of large human joints]

Angioarchitectonics of 127 capsules of large joints in superior (brachial, ulnar, radiocarpal) and inferior (coxofemoral, genicular, talocrural) extremities have been studied using a complex of anatomical and histological techniques and morphometry. As demonstrate the investigations, in the fibrous and synovial membranes of the capsules in these joints, there are certain differences in the architectonics and in depth of the blood network arrangement. In accordance with the diameter of these vessels, density and character of distribution in the capsule membranes of the joints, it is possible to distinguish four circulatory networks. They have numerous anastomoses and form a united volumetric network of vessels. Certain general regularities are noted in the structure of the vascular networks of the capsule membrane in the extremity joints, as well as changes of their angioarchitectonics are revealed as adaptations to age morphofunctional changes in the connective tissue formations of the capsules.
